A tool meant to help answer the question "How lean is my program?"
OWM runs a specified program and samples its performance until completion. Then the final measurements are displayed, and may optionally be saved as a textual report or CSV data.
OWM is not a profiler. It only reports final bulk statistics. These are not precise since after process termination values are not available. Instead it samples roughly 10 times per second until statistics are no longer retrievable.
Saving
When data is saved to an existing report or CSV file it is appended to the end.
Effort is made to be locale-aware when writing reports and CSV data. This means respecting "comma as decimal point" and delimiting output columns with semicolons in such cases. Other locale formats should work automatically as well. In the report text the appropriate "thousands separators" should be used too.
CSV text values are always wrapped in quotes (") with quote characters escaped by doubling (as ""). No other escaping is
attempted.
CSV output files always use the ANSI encoding of the current locale.
Requirements
Requires at least Windows 2000, but some things might fail before Windows Vista.
Only tested on Windows 10.
